Oleksandr Gabrylchuk 02fab4cf9e venus: Implement guest vram blob type. ... Add support of GUEST_VRAM type of blob. These are dedicated heap memory allocations required for vk support on hypervisors that don't support runtime injections of host memory into guest physical address space. The flow of usage: 1) Host VM reserves dedicated heap memory 2) Device get info about memory reservations and report it to guest using mmio registers 3) Guest virtio-gpu driver on starts checks mmio registers for physical address and length of reserved region. Then it reserves it in guest. 4) On each call of vkAllocateMemory() guest driver gets chunk of required memory and send it to host using sg list. It uses one sg entry for 1 blob call. Heap is managed on guest using drm memory manager (drm_mm).
